This application claims the benefit of priority of U.S. provisionalapplication No. 62/736,084, filed Sep. 25, 2018, the contents of whichare herein incorporated by reference.

BACKGROUND OF THE INVENTION

The present invention relates to a glass pipe and, more particularly, toa glass pipe with a protective antibacterial cover and a discrete cap.

Glass pipes are commonly used for smoking tabaco. Glass pipes may easilyslip out of user's hands, fall on the ground, and break. Additionally,ash and burning material can fall out of the bowl of the glass pipe,which may hurt the user or destroy clothing. Another issue with glasspipes is there currently is no protection from heat when lighting thecontents of the pipe, and there are no antibacterial products used inconjunction with the pipe. Therefore, the pipe may become contaminated.

As can be seen, there is a need for an improved gripping and cap for aglass pipe that alleviate the above-mentioned problems.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplatedmodes of carrying out exemplary embodiments of the invention. Thedescription is not to be taken in a limiting sense, but is made merelyfor the purpose of illustrating the general principles of the invention,since the scope of the invention is best defined by the appended claims.

The present invention includes a discrete protected smoking device toreduce tobacco intake and particles, reduce breakage while protectingthe user or clothing from burns.

Referring to FIGS. 1 through 6, the present invention includes a smokingdevice. The smoking device includes a pipe 10 made of an elongated glasstube having an open first end and an open second end. An internalsurface of the elongated glass tube includes a narrowed portion 16defining a narrowed diameter opening. The narrowed portion 16 separateschambers 14, 18 within the elongated glass tube. The chambers 14, 18include a material chamber 14 defined from the second open end to thenarrowed portion 16, and a smoke chamber 18 defined from the narrowedportion 16 to the first open end. The material chamber 14 defines a bowl12 to contain smoking material 50, such as tabaco.

The elongated glass tube includes a cylinder shape having a circularsidewall and two open ends. The elongated glass tube may besubstantially straight or curved. In certain embodiments, the open firstend of the pipe 10 includes an output opening 20 and the sidewallsurrounding the output opening may include a frusto conical shape. Thereduced diameter at the output opening 20 may further reduce inhaledparticles while smoking. Smoking material 50 may be placed within thematerial chamber 14 and lit on fire. Smoke is pulled through thenarrowed portion 16 into the smoke chamber 18 and out the output opening20.

The present invention may further utilize a cap 40. The cap 40 includesan open end and output openings 46. The output openings 46 may bedefined on a partially closed second end of the cap 40. The cap 40 mayfurther include a clip arm 42 extending from the open end so that thecap 40 resembles a pen cap. Therefore, placing on the cap 40 onto thepipe 10 allows the smoking device to resemble a pen, making the presentinvention more discreet when using the smoking device in public. The cap20 may further include a screen or filter.

The smoking device includes a transport position and a smoking position.The transport position includes the cap 40 friction fitted over the opensecond end, and the smoking position includes the cap 40 friction fittedover the open first end. The cap 40 is used as a mouthpiece in thesmoking position and further prevents inhaled particles. When the useris finished smoking, the cap 40 may be removed from the open first endand placed over the open second end. In the transport position, the cap40 may contain tobacco, or ash safely in within the materials chamber16, which reduces the potential to burn the person or fabric and furtherprevents smoking material 50 from falling out.

The pipe 10 of the present invention may further include a polymercoating 30 sealed to an outer surface of the elongated glass tube. Thepolymer coating 30 may be heat shrunk over the outer surface of theelongated glass tube. A heat gun may be used to shrink the polymertubing to conform to the shape of the elongated glass tube. The polymercoating 30 may include anti-bacterial properties and heat resistantproperties. For example, the polymer coating 30 may include polyolefin.The polyolefin coating covers the exposed glass up to the carburetorwhile dissipating heat. In certain embodiments, the coating 30 may beinfused with a scent to disguise the smell of burned tobacco. Forexample, the coating 20 may be infused with a cologne or a perfume toreduce the tobacco smell.

A method of using the present invention may include the following. Afterthe smoking material 50 (tobacco and the like) is inserted into thematerial chamber 14, the cap 40 is placed over the second open end tocontain the smoking material within the material chamber 14. The cap 40also protects the second open end against breaking. To smoke the pipe10, the cap 30 is removed from the second open end and placed over thefirst open end, the exposed smoking material 50 is lit with a lighter,and the user inhales. In this position, the smoke travels through thesmoke chamber 18, passing through the tapered restriction at the firstopen end, further reducing particles while creating a cooling vortex inthe cap 30. The smoke passes through the cap screen and out of theoutput holes 46.

It should be understood, of course, that the foregoing relates toexemplary embodiments of the invention and that modifications may bemade without departing from the spirit and scope of the invention as setforth in the following claims.
